There's another thread on these somewhere.
I have been testing and using them for a few weeks now and they seem to suit my Walther LG300 very well.
One thing to watch, and I have been in touch with H&N about this, is that the skirts can get dented / damaged in transit. I sort through all mine before use and the bent ones are used for plinking.
I now have a decent stock and will be using them for the foreseeable future.
